Reactions of dioxomolybdenum(VI) hydroxamate and thiohydroxamate complexes with organohydrazines. Structures of oxohydrazido(2−) complexes [MoO(N2Ph2)(PhC(X)N(Me)O)2], where X = O and S, and of the bis-diazenido complex [Mo(N2Ph)2(PhC(S)N(Me)O)2]

New Piano Stool cis-Bis(organohydrazido) Complexes of Molybdenum. X-ray Structure of [(η5-C5H5)Mo(NNPh2)2(PPh3)]+CF3SO3-

“…A number of coordination complexes containing the cis -{M(NNRR‘) 2 } z + functional unit with two η 1 -bonded hydrazido ligands (R, R‘ = alkyl, aryl) have been characterized, particularly when M = Mo, − Re, − W, ,, V, Nb, and Ta . However, to the best of our knowledge, organometallic compounds containing such a unit have not been reported .…”
